And a good thing too. One of the best things about GW Messenger versus many other IM offerings out there is its simplicity. It's an instant messaging system, not a multimedia/multiprotocol/web browser/security nightmare, like Yahoo Messenger, etc. You don't have to worry about opening up six different vectors for attacks every time someone launches the thing.

If you really want this sort of goofiness IN the IM client, you can always use an alternate client that supports multiple protocols, such as GAIM, or Trillian, both of which can talk to GroupWise Messenger.
